Which one of the following equations is correct for the reaction $N_{2(g)} + 3H_{2(g)} \longrightarrow 2NH_{3(g)}$?

  • A
    $3 \frac{d[NH_3]}{dt} = 2 \frac{d[H_2]}{dt}$
  • B
    $3 \frac{d[NH_3]}{dt} = 3 \frac{d[H_2]}{dt}$
  • C
    $2 \frac{d[NH_3]}{dt} = -3 \frac{d[H_2]}{dt}$
  • D
    $3 \frac{d[NH_3]}{dt} = -2 \frac{d[H_2]}{dt}$

The average rate of reaction $2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$ is written as

In the reaction,$N_{2} + 3H_{2} \longrightarrow 2NH_{3}$,the rate of disappearance of $H_{2}$ is $0.02 \ M/s$. The rate of appearance of $NH_{3}$ is (in $M/s$)

If the instantaneous rate of reaction is given as $-\frac{1}{a} \frac{d[A]}{dt} = -\frac{1}{b} \frac{d[B]}{dt} = \frac{1}{c} \frac{d[C]}{dt} = \frac{1}{d} \frac{d[D]}{dt}$,then the reaction is represented as:

The instantaneous rate of a reaction is given by $-\frac{1}{2} \frac{d[x]}{dt} = -\frac{d[y]}{dt} = \frac{1}{2} \frac{d[z]}{dt}$. Identify the reaction.
